& Sciences Publication Pvt. Ltd. Research on Rapid Image Recognition Method of Foreign Fibers in Lint

Abstract—An efficient online method of detecting the foreign fibers in lint is proposed. In this method, Look Up Table is used to reduce the time consumption of transformation from RGB color space to HSI color space effectively. Using the improved two-dimensional Otsu algorithm to segment and recognize the image of foreign fibers in Hue and Saturation of HSI color space. Experimental results show that, compared with the original two-dimensional Otsu algorithm and the fast two-dimensional Otsu algorithm, the proposed method meets the requirement of real-time and improves the accuracy effectively
